Hard to say before we can actually play the new patch, but it shouldn't get any worse, probably even better.

But does anyone else feel like that they are missing hits every now and then with this build, even with RT? I mean when i'm in middle of a pack and i hit them, sometimes there seems to be no hits registered, died few times to that allready. Or is that desync? I usually play with GS and theough i'd try this for a chnage, and it's fun, but not when you can't hit the mobs.

Thanks for the reply Ziggy, yea I'm running Carcass Jack and so far it's working pretty well. another question: Do you think that concetrated effect could be a potential good gem to link with infernal blow?

I just made my build with the new skilltree and it looks like this at lvl 78:

It's pretty much the same build Ziggy made at lvl 79 with a few changes only:

1: I went around the resistances node near diamond skin for a extra point.
2: I thought a lot on picking berseking but I ended up saving the 6 points to go for smashing blows and save a single point.
3: I picked up unwavering stance, no reason to not pick it up due to it's new location.
4: From the original build there were a few ways to go for Iron reflexes, I decided to pick the way that takes 4 points rather than 5 and nets a single Armor+evasion node rather than stats node only.
5: Finally, due to the frenzy node being only 1 point away from my build I decided to pick it up and try running a The blood dance on my character, it's pretty much the same as getting a 1% life regen node + 2% attack and movement speed.

I also tried avatar of fire with no success because it makes you deal no physical damage and I couldn't keep the mana up without the physical damage mana leech from my ring.

Finally, while my defense dropped a bit for running the blood dance but I felt like the life regen makes more than up for it, it's not that hard to keep all the frenzy charges at all times(just keep the charges up by killing trash mobs and use frenzy just once when you're against harder mobs or running out of them).
